The teenager's most recent problem might cause some concern at Elland Road.
Leeds United fans are rightly excited for the upcoming season. The club have made some good signings in the off-season and they seem to be settled on new manager Uwe Rosler, with a more settled backroom hopefully having a positive impact on the first-team results.
Of course one major positive is that of the young talent at the club. The likes of Sam Byram, Charlie Taylor and Alex Mowatt are all top talents – as is Lewis Cook.
The midfielder looks a real talent with the ability to be a star for years to come at Elland Road.
However he limped out of action yesterday against Hoffenheim and it is important to remember the fragility of his age.
He ended last season on the treatment table after getting injured on international duty. Neil Redfearn’s attempts to wrap him up in cotton wool proved to be futile. Now he is struggling with another knock it is a timely reminder that he is just 18-years-old and must be handled with care.
Trouble for Leeds?
The club allowed Rudy Austin an exit in the summer and now Luke Murphy has had knee surgery, so Leeds are looking to be short of central midfield options after Cook’s issue. Tomasso Bianchi is also out injured so the likes of Kalvin Phillips, new signing Tom Adeyemi and Casper Sloth might be called upon when the season begins this month.
Leeds have cover in midfield, but considering the age of both Cook and Mowatt it must be wondered whether they in fact need a more experienced and sturdy option as well as their current crop if they are to be successful this term.
